Which two database engines are provided by Amazon Elasticache?

MySQL and Oracle
Redis and Memcached
PostgreSQL and Aurora
MariaDb and Microsoft SQL Server

The correct answer is: Redis and Memcached

Amazon ElastiCache is a fully managed in-memory data store service provided by AWS, and it is primarily designed to enhance the performance of applications by allowing them to access data with minimal latency. The two database engines that are specifically provided by ElastiCache are Redis and Memcached. Redis is a key-value store known for its advanced data structures and in-memory data storage capabilities, making it suitable for use cases that require rapid data retrieval and processing, such as caching, real-time analytics, and session management. Memcached, on the other hand, is a simpler key-value store that is particularly effective for caching objects and improving the performance of web applications by minimizing database load. The other options presented involve traditional relational database engines, which are not the focus of Amazon ElastiCache. Instead, they fall under different AWS services, such as Amazon RDS (Relational Database Service), which supports engines like MySQL, PostgreSQL, Oracle, and SQL Server. This distinction is key to understanding the role of ElastiCache in AWS architecture, reinforcing that it is specifically for in-memory caching with Redis and Memcached, making the chosen answer accurate.
